DETAILED DESCRIPTION OF FIGURES

A user may have an overall bed comfort requirement for their overall body, but may also have requirements for localized body comfort. The user may have a unique situation that may require various comfort levels within a bed. For example, the user may desire a general medium firmness for the bed but may have additional requirements of firmer support in the users back area to provide additional back support for total body comfort.

A bed that may have interchangeable foam springs may allow the user to interchange different foam spring firmnesses to provide firmness differences that may compensate for local body areas requiring different support than the overall bed. To aid in the placement of the various foam spring firmnesses there may be facilities to hold the foam springs in the required locations and a method of determining where to place the various foam springs to provide the users desired comfort. There may be a plurality of methods to place the different foam spring firmness into the bed that may include trial iteration, a questionnaire, a software application, or the like. The plurality of foam spring placement methods may be performed by the user alone or may be done in combination with a bed enterprise, service enterprise, manufacturer, or the like.

One of the goals of the customizable firmness bed may be to provide the user with an apparatus and method of creating a bed with different local firmnesses that may compensate for different comfort requirements the user may have. The user may require less firmness in one location of the bed while also requiring firmer support in other locations of the bed. As described below, methods and systems are described that may allow the placement of individual firmness foam springs in a bed to provide total comfort requirements to a user.

Another goal may be to provide a method of determining where to place the various firmness foam springs within the bed to meet the users requirements. As described below, the user may provide input for the type or foam spring and foam spring firmness that may be required and a foam spring orientation may be determined using the users input.

Referring now to FIG. 1, a block diagram of a bed facility 102 and associated components is shown. In embodiments, the bed facility 102 may include a containment facility 104, attachment facility 120, regions 122 of foam springs, and a plurality of foam springs 108. The foam springs 108 may also include materials that may provide health benefits to the user such as activated carbon 110, tourmaline 112, and magnets 114. Additionally, there may be a foam spring orientation application 118 to aid in the placement position of the plurality of foam springs 108. In an embodiment, the containment facility 104 may have the shape of a bed mattress with a bottom, top, and sides and may provide the shape in which the foam springs 108 may be placed. In an embodiment, the foam springs may be oriented into different regions 122 where the different regions may contain different firmness foam springs 108. The attachment facility 120, as will be described below, may provide openings in which the foam springs 108 may be placed. The attachment facility 120 openings may provide a pattern of openings to allow foam springs of various firmness to be placed within the containment facility 104. As shown in FIG. 1, the plurality of foam springs 108 may include firmness 1, firmness 2, through firmness N to provide various firmnesses within the bed facility 102. The foam spring orientation application 118 may be used by the user, sales enterprise, manufacturer, or the like to determine where the plurality of foam springs 108 should be placed to meet the users comfort requirements.

A bed facility 102 may be any type of bed that may provide a comfortable position for a user to rest, sleep, sit, convalesce, or the like. The bed facility 102 may include a standard bed, an adjustable bed, or the like. The bed facility 102 may be in any shape or size that may include a crib bed, twin bed, full size bed, queen size bed, king size bed, or the like. In an embodiment, the bed facility 102 may typically include a mattress, box spring, support frame, and the like. In an embodiment, the mattress may include a material top layer (e.g. foam or material), material bottom layer, springs, foam layers, and the like.

In an embodiment, a standard non-adjustable bed may be any bed that maintains a single rigid position that may not be capable of changing its shape or position. Additionally, the non-adjustable bed may be any rigid shape that may have a non-flat configuration.

In an embodiment, an adjustable bed may be a type of bed that is capable of adjusting at least one aspect of the bed shape such as a head section, a foot section, leg section, a torso section, or the like. In an embodiment, there may be a control interface that a user may use to adjust the position of at least one aspect of the bed.

In an embodiment, the foam springs 108 may be any type of soft foam that may include latex foam, urethane foam, visco-elastic foam, polyurethane foam, or the like. In an embodiment, the foam springs 108 may be used for bedding, pillows, chairs, couches, or the like. In an embodiment, the foam springs 108 may be considered a foam support for the bed facility 102.

In an embodiment, the foam springs 108 may be made of the solid foam material but may additionally have interior openings, exterior openings, interior and exterior opening, or the like. The openings may not be important to the firmness of the foam spring 108 but may be useful for manufacturability of the foam spring, providing space for added foam spring movement, contain health related materials, and the like.

In an embodiment, a mattress outer case may be a part of the bed facility 102 mattress that provides the volume space to place the foam springs 108. In an embodiment, the mattress outer case may be the mattress, a separate bed structure from the mattress, or the like. The mattress outer case may have a shape that is substantially the same as the bed facility 102. In an embodiment, the foam spring 108 may have a height that may equal to the height of the mattress outer case, may be a portion of the height of the mattress outer case, may have a height greater than the mattress outer case, or the like. In an embodiment, the cross section of the foam spring 108 may have any shape that may include a round shape, a square shape, a hexagon shape, an octagon shape, a star shape, an oval shape, or the like. In an embodiment, a plurality of foam springs 108 may be contained within the mattress outer case. The plurality of foam springs 108 may be all the same shape, a combination of shapes, or the like. In some cases, the foam spring 108 shapes may be combined to provide for spaces between the foam springs 108 that may allow the foam springs 108 to have freedom of motion. For example, the plurality of foam springs 108 may be all circle shaped or a combination of circle and oval shaped foam springs 108 to provide spaces between the foam springs 108 to allow motion areas for the foam springs 108. In other cases, it may be desired for the foam springs 108 shapes to be selected where the foam springs 108 are in close contact with each other to allow each of the foam springs 108 to support the adjacent foam springs 108. For example, the plurality of foam springs 108 may be all square foam springs 108 that contact adjacent foam springs 108 on all four sides; this may provide support to the foam spring 108 and all the adjacent foam springs.

In an embodiment, the plurality of foam springs 108 contained within the mattress outer case may have a plurality of different firmnesses. In an embodiment, the foam spring 108 firmness may be defined by an indentation load deflection (ILD) value, indentation force deflection (IFD) value, foam density, or the like. IFD, and in a similar manner ILD, is defined as the amount of force, in pounds, required to indent a fifty square inch, round surface into a foam material a certain percentage of the foam material total thickness. IFD may be specified as the number of pounds at a specific deflection percentage for specific height foam. For example, the IFD for a certain foam may be defined as 25 pounds/50 in² at a 25% deflection on a four inch thick piece. In an embodiment, the IFD may be influenced by the thickness of the foam material, the size of the material, and the like. For some types of materials, such as latex foam, the ILD value may correlate with the density of the material used. For others, the ILD may be less dependent, or even independent, of the density of the material used.

The firmness may also be measured or described by the density of the foam, in pounds per cubic foot, kilograms per cubic meter, or some other relevant standard. Although the density may not be a direct measurement of firmness, it may have a direct relationship to firmness. For example, a 110 kg/m3 density barrel may be firmer than a 95 kg/m3 barrel and the 95 kg/m3 barrel may be firmer than a 80 kg/m3 density barrel, and the like.

In an embodiment, the plurality of foam springs 108 may be configured within the mattress outer case to provide localized variable firmnesses for the bed facility 102. In an embodiment, the firmness of a bed facility 102 may be varied to provide comfort for a user that may be experiencing discomfort as a result of an accident, arthritis, surgery, chronic conditions, a neck condition, a knee condition, a sleep disorder, a disease, or the like. In some cases, the discomfort experienced by the user may not be static but may be part of a changing condition that may have the user experiencing more or less discomfort over time.

In many cases the discomfort the user may experience may be a local discomfort such as lower back pain, hip pain, neck pain, shoulder pain, and the like where it may be advantageous to have different firmness in these areas to provide an improved resting comfort in the local position. For example, the user may experience lower back pain and the plurality of foam springs 108, with a certain firmness, may be configured to provide less firm or firmer support in the lower back area to help provide a comfortable resting position.

In an embodiment, the user's discomfort may change over time, and the plurality of foam springs 108 may be modified to compensate for the changing user condition. For example, if the user is suffering from lower back pain, the initial foam spring 108 configuration may provide firmer support in the area of the lower back to position the back for improved healing. Over time, the user's lower back may improve and the foam springs 108 firmness in the area of the lower back may be modified by gradually providing less firm support until the form spring 108 firmness is the same as the remainder of the bed facility 102.

In an embodiment, when considering the location to place the various foam spring 108 firmnesses, the user's physical characteristics (e.g. height, weight, body shape, gender) may be considered for the proper placement and firmness of the foam spring 108. For example, the placement for the foam springs 108 for a user's lower back may be influenced by the user's height, typical sleeping position, size of the bed, shape of the bed, location the user sleeps on the bed (e.g. towards the head or foot of the bed), and the like.

It may be understood that the foam spring 108 configuration may be varied to account for more than one user condition of discomfort. For example, a user may have more than one body location that is effected by arthritis. The plurality of foam springs 108 may be configured to provide comfortable resting conditions to any or all of the body locations that the user desires discomfort relief. As these conditions may improve or worsen over time, the user may be able to change the foam spring 108 configuration, change the firmness of the foam spring 108 in certain bed facility 102 locations, or the like. As another example, a user may be experiencing discomfort from a chronic condition (e.g. arthritis) and a short-term condition (e.g. surgery). As the short term condition improves, the foam springs 108 in the short-term location may be changed as needed to provide the user with the desired comfort. In a similar manner, as the chronic condition may change with time, the foam springs 108 may be changed in these locations to provide the best comfort position for the user.

In another embodiment, the springs used within the bed facility 102 may be pneumatic or hydraulic springs that may be have adjustable firmness settings. A bed facility 102 may have a pattern of pneumatic or hydraulic springs that may be orientated using a containment facility 104. In an embodiment, the user may be able to adjust the individual firmnesses of the pneumatic or hydraulic springs to meet the comfort requirements of the user. In an embodiment, there may be a computer device interface where the user may be able to indicate the required firmness for certain locations of the bed facility 102. In an embodiment, the computer device may be a desktop computer, laptop computer, server, webserver, personal digital assistant (PDA), smartphone, handheld computer, or the like. The computer devices may include connections to a network for accessing other computer devices that may store or manage bed facility 102 information. In an embodiment, the networks may include a WAN, LAN, Internet, intranet, peer-to-peer, or other network connecting computer devices. In an embodiment, the computer device and networks may be wired or wirelessly connected. In an embodiment, using the network, the user may be able to access computer devices on the network to receive spring firmness settings. For example, the user may access the Internet from the computer device and may download a particular set of spring firmness settings that may match a desired comfort requirement. In an embodiment, the computer device interface may show a grid substantially the same as the orientation of the pneumatic or hydraulic springs where the user may be able to indicate the firmness of the individual springs, groups of springs, zones of springs, areas of springs, the entire bed facility 102, or the like. In an embodiment, the user may work with the computer device interface using a keyboard, mouse, joystick, touch screen, or other input device. In an embodiment, based on the user's indications, the computer device interface may control the pressure of the individual pneumatic or hydraulic springs to provide the desired comfort. In an embodiment, there may be preset firmness configurations that may be selected on the computer device interface; the preset configurations may be user set, historical settings saved by the computer device, preset at the manufacturer, preset at the bed facility 102 enterprise, or the like. In an embodiment, the user may change the firmness configuration as often as the user requires.

In an embodiment, the foam spring 108 attachment facility 120 may be used to provide connection to adjacent foam springs 108, connection to the containment facility 104, or the like to assure the maintaining plurality of foam springs 108 orientation within the mattress outer case. As previously discussed, the plurality of foam springs 108 may have certain orientations that may provide various foam spring 108 firmnesses to provide relief for user discomfort. In an embodiment, a method and system of foam spring 108 containment may be used to assure that the preferred orientation of the plurality of foam springs 108 does not change, move, realign, or the like over time and use of the bed facility 102. In an embodiment, the foam springs 108 may directly connect together using mechanical attachment, direct attachment, or the like. In an embodiment, the containment facility 104 may be used to connect to the foam springs 104 using the geometric shape, the mechanical attachment device, the direct attachment device, or the like.

In an embodiment, the containment facility may be a patterned holding device that may provide positioning for the foam springs 108 within the mattress outer case. The pattern may provide the orientation of the foam springs 108 within the mattress outer case and therefore may provide the locations where various firmness foam spring 108 may be located. In an embodiment, the foam springs 108 may be placed only in the containment facility 104, placed without the containment facility 104, placed as a combination of in the containment facility 104 and without the containment facility 104, or the like. In an embodiment, the foam springs 108 that may be placed without the containment facility 104 may directly connect to adjacent foam springs 108, may not directly connect to adjacent foam springs 108, or the like. In an embodiment, the containment facility 104 may have the same shape as the mattress outer case, mattress, bed facility 102, or the like.

In an embodiment, the containment facility 104 may contain a preset pattern, an adjustable pattern, a plurality of patterns, or the like. In an embodiment, more than one containment facility 104 may be used within a mattress outer case. The individual containment facilities 104 may contain different patterns, may have different sized openings for different sized foam springs 108, or the like. In an embodiment, more than one containment facility 104 may be connected together to form a larger containment facility. For example, a first containment facility 104 may have a square pattern for the foam springs 108 and a second containment facility 104 may have a hexagon pattern for the foam springs 108. The square patterned containment facility 104 may be useful for a user's back area while the hexagon patterned containment facility 104 may be useful in a user's shoulders and hips. In an embodiment, the more than one containment facilities 104 may be connected together to form a larger containment facility 104, may be independent from each other, may be a combination of connected and independent containment facilities 104, or the like. In an embodiment, the more than one containment facility 104 may be combined to provide localized support to meet a user's requirement for discomfort relief. For example, within a mattress outer case, square containment facilities 104 may be used at a users head, back, and leg locations while the hexagon containment facilities may be used for the user's shoulders and hips. This configuration capability may provide for improved targeting of certain firmness foam springs 108 to a users requirement.

In an embodiment, the containment facility 104 may be made from materials, non-rigid materials, a combination of rigid and non-rigid materials, and the like. In an embodiment, a rigid containment facility 104 may be made of metal, plastic, or the like. In an embodiment, a flexible containment facility 104 may be a cable, a rope, a strap, a web, an elastic material, foam, or the like. In an embodiment, the containment facility 104 may include both rigid and non-rigid materials. For example, the containment facility 104 may be rigid but may contain non-rigid materials to connect to the foam springs 108. One example of a possible embodiment of the present invention is shown in FIGS. 4 a and 4 b. The density of the latex foam is varied in different cylinder-shaped components that may be referred to as “barrel coils.” The barrel coils may vary in density and therefore in their ILD (softness/firmness rating) because the density of latex foam has a direct correlation with ILD. Individually molded latex barrels/cylinders are connected to each other by a fabric webbing. Such fabric webbing is then pulled through the foam encasement on the sides of the mattress to hold the barrels in place. This is only one possible embodiment of the present invention, and it should be understood that many different configurations and materials may be used.

In another embodiment of the containment facility 104 may be a layer of foam with a pattern of holes for placing the foam springs 108; the layer of foam may have substantially the same shape as the bed facility 102. The foam springs 108 may be attached to the layer of foam using Velcro, tape, double stick tape, glue, elastic, matching geometric patters in the layer of foam and foam spring 108, or the like. In an embodiment, there may be more than one layer of foam used to contain the foam springs 108. In an embodiment, the layer of foam may connect to the foam springs 108 in predetermined locations on the foam springs 108. For example, a single layer of foam may contact the foam springs 108 at the center of the foam springs 108. In another example, if two layers of foam are used, the contact may be at the top and bottom of the foam spring 108.

In another embodiment, the containment facility 104 may be a side foam rail 1112, a foam bottom layer, a foam top layer, or the like that include indentations in which the foam spring 108 may fit. As an example shown in FIG. 11E, the side foam rails 1112 may have an indentation shape 1114 to hold the same shaped foam spring and the foam springs 108 may fit into the side rail indentations 1114 to hold the foam springs 108 in the correct orientation. FIG. 11E more particularly shows an embodiment of an indentation shape 1114 to hold the foam spring 108 having a shape depicted in FIG. 2. Separately from or in combination with the indented side rails 1112, the top foam layer and/or the bottom foam layer may have indentations in the shape of the foam spring ends to hold the foam springs in the correct orientation. In an embodiment, the indentations in the top and/or bottom foam layers may provide a nesting location for the foam spring to provide orientation positioning.

In another embodiment, the containment facility 104 may hold a combination of foam springs 108 and metal inner springs. In an embodiment, the metal inner springs may be used side by side with the foam springs, the metal inner springs may be under the foam springs 108, the metal inner springs may be above the foam springs 108 or the like. The metal inner springs may be used to provide added support to the user, localized support to the user, or the like.

In an embodiment, it may not be required that each patterned containment facility opening have a foam spring 108.

In an embodiment, the containment facility 104 may have pattern openings that provide locations for the various foam springs 108 firmness patterns that may be required by the user. In an embodiment, the foam spring 108 firmness pattern may be determined using certain containment facilities 104. For example, before proceeding with the determination of the foam spring 108 requirements, the type of containment facility 104 may be determined that may provide the patterned opens to support the foam spring 108 firmness patterns. In considering the users comfort needs, a certain containment facility 104 may be selected that may provide for the proper targeting of foam springs 108 in the area required. For example, a user may select a containment facility 104 the has a pattern that provides proper general support to his or her back but may also have foam spring 108 openings that may be used to target a particular firmness to the users shoulders.

A person knowledgeable in the art may understand that the containment facility 104 and foam spring 108 combinations may take many different configurations to provide the user comfort required.

In an embodiment, the bed facility 102 enterprise, bed facility 102 setup enterprise, the bed facility 102 manufacturer, or the like may offer predetermined foam spring 108 patterned bed facilities 102. There may be a number of standard foam spring 108 pattern bed facilities 102 that may be historically preferred, provide standard relief for particular user discomfort, or the like. In an embodiment, the standard bed facility 102 may have a certain number of areas or zones that have foam spring 108 firmnesses that may provide comfort to users with common comfort requirements. For example, a predetermined foam spring 108 pattern may be a medium firmness foam spring 108 under the head/shoulders, a firmer foam spring 108 under the back, and a less firm foam spring 108 under the legs. In another example, there may be predetermined foam spring 108 patterns for hip, shoulder, neck, leg, or the like comfort. In an embodiment, a user may purchase a standard bed facility 102 with a predetermined foam spring 108 pattern that may meet the user's requirements and may make firmness adjustments to the foam spring 108 pattern with purchased replacement foam springs 108.

In an embodiment, the bed facility 102 may have a uniform (or substantially uniform) firmness by using foam springs 108 of all (or substantially all) the same firmness.

A foam spring orientation application software 118 may be used to determine the placement of the plurality of foam springs 108 within the mattress outer case. In an embodiment, the foam spring orientation application software 118 may be a stand-alone application, a server application, a web application, or the like. In an embodiment, the plurality of foam springs 108 may be of differing firmnesses and the foam spring orientation application software 118 may be used to determine the proper placement of the different foam spring 108 firmnesses to meet the users comfort requirements. For example, the user may require certain locations of the mattress to be less firm, more firm, or the like to help provide the proper support for a part of his or her body that may be experiencing discomfort such as a hip, shoulder, back, neck, knee, or the like. The user may have had an accident, surgery, suffer from arthritis, or the like and different firmnesses within the bed facility 102 may be required to provide the proper comfort for these areas of discomfort.

In an embodiment, the foam spring orientation application software 118 may present questions to a user to determine the comfort requirements of the user's bed facility 102. The questions may be presented to the user as a paper questionnaire, a computer questionnaire, indicating on a chart of the body the areas needing comfort consideration, or the like. In an embodiment, the user may interact with the foam spring orientation application 118 at the user's location, at the bed facility 102 enterprise, at the bed facility 102 setup enterprise, at the bed facility 102 manufacturer, or the like.

In an embodiment, the computer device may be a desktop computer, a laptop computer, a tablet computer, a kiosk, a PDA, a smart phone, or the like. In an embodiment, the computer device may work with a network that may be a LAN, WAN, Internet, intranet, wireless, wired, or the like. In an embodiment, the computer device interactive questionnaire may present additional questions to the user based on the answer to a previous question. For example, a first question may ask if the user suffers from discomfort in his or her back. If, for example, the user answers yes, the questionnaire may continue to ask questions that are particular to back discomfort such as location of pain, pain levels, if the pain is sharp, if the pain is dull, if the pain increases with time, and the like.

In an embodiment, the user may indicate on a body chart the areas of discomfort that may require various foam spring 108 firmnesses. In an embodiment, the body chart may be in paper form, on a computer device, or the like. In an embodiment, the body chart operated on a computer device may incorporate a touch screen to enable the user to touch the locations on the computer screen that may require addition comfort control. In an embodiment, the user may indicate the location, the type of discomfort, the intensity of discomfort, and the like that the form spring orientation application software 118 may be able to interpret into bed facility 102 firmness requirements. In an embodiment, the body chart may be divided into a grid, sections, zones, or the like to allow the user to define the location of discomfort.

In an embodiment, after the questionnaire is complete, the application software 118 may determine at least one configuration of foam springs 108 for the bed facility 102. The configuration my include foam springs 108 of varying firmness to provide a firmness configuration that may match the firmness requirements of the user. For example, if the user indicated in the questionnaire that he or she suffered from back pain in the lower back area, the foam spring orientation application software 118 may configure less firm or firmer foam springs in the area of the lower back. The remainder of the bed facility 102 may be configured to have a standard firmness to properly support the remainder of the user's body. This configuration of varying firmness across the bed facility 102 may provide the user with a comfortable position to rest, sleep, or the like.

In an embodiment, after the foam spring orientation application software 118 has determined the foam spring 108 configuration for the user, a test configuration may be setup in the bed facility 102 enterprise for the user to try the form spring 108 configuration. Based on the user trying the foam spring 108 configuration at the bed facility 102 enterprise, the foam spring 108 configuration may be modified to improve the bed facility 102 comfort.

In an embodiment, the foam spring 108 configuration may be manually modified by the user or the bed facility enterprise by interchanging form springs 108 and retrying the comfort of the bed facility 102 until a desired comfort has been reached. In another embodiment, the answers to the foam spring orientation application software 118 may be revised and the foam spring orientation application software 118 may provide a new foam spring 108 configuration for the user to try. In another embodiment, the foam spring orientation application software 118 may have provided more than one foam spring 108 configurations and the user may try at least one of the additional configurations to determine if one of the additional configurations provides the desired comfort.

In an embodiment, the foam spring orientation application software 118 may be a web application; the web application may store the final foam spring 108 pattern configuration. In an embodiment, if the foam spring 108 pattern requires modification, the bed facility 102 enterprise, bed facility 102 manufacturer, bed facility 102 setup enterprise, user, or the like may use the stored foam spring 108 pattern information to revise the foam spring 108 pattern using the web accessed foam spring orientation application software 118. In an embodiment, the web-based application may have the same questionnaire that was used to determine the original foam spring 108 pattern. In an embodiment, the web-based foam spring orientation application software 118 may be accessed, with the user's stored information, and the information revised to match the most recent user information. In an embodiment, the web-based foam spring orientation application software may determine at least one revised foam spring 108 pattern.

In an embodiment, after the revised foam spring 108 pattern is determined, the new foam springs 108 that may be required by the revised foam spring 108 pattern may be order by the web-based foam spring orientation application software. In an embodiment, the revised foam spring 108 pattern may be assembled by the bed facility 102 manufacturer, the bed facility 102 enterprise, the bed facility 102 setup enterprise, user, or the like.

A bed facility 102 may be any type of bed that provides a comfortable position to a user for resting, sleeping, sitting, convalescing, or the like. The bed facility 102 may be a standard non-adjustable bed, an adjustable bed, and the like. In an embodiment, the bed facility 102 may include a mattress, box spring, support frame, and the like. In an embodiment, the mattress may include a material top layer (e.g. foam or material), springs, foam layers, and the like. The bed facility 102 may be used as a supportive facility for resting and sleeping by users of any age and may include infant beds (e.g. cribs), children beds, bunk beds, adult beds, and the like. In an embodiment, beds may be made of various different sizes such as twin, full, queen, king, and the like for different situations and user requirements. The bed sizes may be industry standard sizes but there may also be more than one standard size for a bed type such as a long twin bed verses a standard sized twin bed.

A standard non-adjustable bed may be any bed that maintains a single rigid position that may not be capable of changing shape or position. In an embodiment, the standard non-adjustable bed may typically be used in a bedroom for sleeping, resting, or the like and may provide a flat horizontal surface for the user to lie down on. Additionally, the non-adjustable bed may be a single rigid shape that may have a non-flat configuration. Typically, the standard non-adjustable bed may be rectangular in shape, but may also be in other shapes such as round, square, or the like.

An adjustable bed may be a type of bed that capable of adjusting at least one aspect of the bed shape such as a head section, a foot section, leg section, a torso section, or the like. In an embodiment, there may be a control interface that a user may use to adjust the position of at least one aspect of the bed. In an embodiment, the bed position adjustment may be to provide a more comfortable position to the user for performing a task (e.g. writing at a work station), relief from pain, watching TV, provide a different sleeping position, improved blood circulation (e.g. elevated head or feet), and the like. In an embodiment, the bed structure may be flexible, hinged, or the like to provide locations for the adjustable bed to move into different positions.

In an embodiment, the bed facility 102 may use a mattress that contains foam springs 108 to support the user. In an embodiment, the foam spring 108 may be made of any type of soft foam that may include latex foam, urethane foam, visco-elastic foam, polyurethane foam, or the like. In an embodiment, the foam spring 108 may be contained in a mattress outer casing; the mattress outer casing may be in the shape of the bed. In an embodiment, the foam spring 108 may provide direct support to the user, provide indirect support by supporting an over layer of material, or the like. In an embodiment, the foam spring 108 may typically be of a height to fit between the top and bottom surfaces of the mattress outer casing. In another embodiment, the foam spring 108 may be a portion of the height of the mattress outer casing and more than one foam spring may be placed on top of another to fill the space between the top and bottom of the mattress outer casing.

In an embodiment, the foam spring 108 may have a cross sectional shape that may include round, square, hexagon, octagon, star shaped, oval, or the like. In an embodiment, foam springs 108 may be used in any facility that a user may require soft supportive characteristics such as beds, pillows, chairs, couches, and the like. In an embodiment, there may be a plurality of foam springs 108 used in a mattress outer casing to provide support to a user. The plurality of foam springs that may be used within the volume of the mattress outer casing may be a combination of cross sectional shapes. For example, the mattress outer casing volume may use a combination round and oval shaped foam springs 108 to provide a different foam spring 108 configuration to different parts of the mattress. In an embodiment, the plurality of foam springs 108 may fit together such that there may be spaces between the foam springs 108; the spaces may provide freedom of motion for the plurality of foam springs. In another embodiment, the shape of the foam springs 108 may be selected that provides for the foam springs 108 to fit tightly together; the tight fit may allow each foam spring 108 to provide support to adjacent foam springs 108. In an embodiment, the cross sectional shape of the foam springs 108 selected for placement within a mattress outer casing may provide for differing support characteristics to the user. For example, looser fitting foam springs 108 may provide for a softer support structure to the user while the tighter fitting foam springs 108 may provide a firmer support structure.

In an embodiment, the foam spring 108 may be solid foam, may contain interior openings, may contain exterior openings, may contain a combination of interior and exterior openings, or the like. In an embodiment, the foam spring 108 interior and exterior openings may not influence the spring foam 108 firmness but may be used for manufacturability, to provide space to allow movement of the foam spring 108, or the like. For example, an interior opening of the foam spring 108 may be used during manufacturing to provide for mold shapes, allow additional area for air injection, or the like. In an embodiment, the interior and exterior openings may be used to provide holding area for health benefit materials such as activated carbon, tourmaline, magnets, and the like.

In an embodiment, the foam springs 108 may have differing firmness that may be defined by an indentation load deflection (ILD) value, indentation force deflection (IFD) value, foam density, or the like. IFD, and in a similar manner ILD, is defined as the amount of force, in pounds, required to indent a fifty square inch, round surface into a foam material a certain percentage of the foam material total thickness. IFD may be specified as the number of pounds at a specific deflection percentage for specific height foam. For example, the IFD for a foam may be defined as 25 pounds/50 in² at a 25% deflection on a four inch thick piece. In an embodiment, the IFD may be influenced by the thickness of the foam material, the size of the material, and the like.

The firmness may also be measured or described by the density of the foam, in pounds per cubic foot, kilograms per cubic meter, or some other relevant standard. Although the density may not be a direct measurement of firmness, it may have a direct relationship to firmness. For example, a 110 kg/m3 density barrel may be firmer than a 95 kg/m3 barrel and the 95 kg/m3 barrel may be filmier than an 80 kg/m3 density barrel, and the like.

In an embodiment, the different IFD foam density, or the like, and therefore foam spring 108 firmness, may be varied or adjusted by using different density foam, different types of foam, or the like. In an embodiment, the foam spring 108 density may be varied by using different percentages of air when manufacturing the foam spring 108; the amount air used during the foam manufacture may provide the amount or size of cells within the foam spring 108. For example, a foam spring 108 with more air, and therefore more foam cells, may provide for lower density foam and therefore may be less firm.

In an embodiment, the foam spring 108 may include an attachment facility 120 to allow more than one foam spring 108 to be associated with other foam springs 108 within a mattress outer casing; the attachment may be used to maintain the orientation of one foam spring 108 to another foam spring 108, the alignment of various firmness foam springs 108, or the like. In an embodiment, the attachment facility 120 may be a feature on the outer surface of the foam spring 108 such as a geometric shaped raised foam area, geometric shaped recessed foam area, attached Velcro material, mechanical snaps, clips, buckles, glue, adhesive, tape, or the like.

A containment facility 104 may be a mechanical device that may be used to contain, orient, and maintain the plurality of foam springs 108 in a pattern within the volume of the mattress outer casing. In an embodiment, the containment facility 104 may be a rigid device, semi-rigid device, flexible device, or the like that may be preset, set by the user, preset and adjusted by the user, or the like. In an embodiment, a rigid containment facility 104 may be made of metal, plastic, or the like. In an embodiment, a flexible containment facility 104 may be a cable, a rope, a strap, a web, or the like. In an embodiment, the rigid and flexible containment facilities 104 may be combined by having a rigid structure such as a plastic patterned containment facility 104 combined with a flexible component such as a strap to attach to the foam spring 108.

The configuration my include foam springs 108 of varying firmness to provide a firmness configuration that may match the firmness requirements of the user. For example, if the user indicated in the questionnaire that he or she suffered from back pain in the lower back area, the foam spring orientation application software 118 may configure less firm or firmer foam springs in the area of the lower back. The remainder of the bed facility 102 may be configured to have a standard firmness to properly support the remainder of the user's body. This configuration of varying firmness across the bed facility 102 may provide the user with a comfortable position to rest, sleep, or the like.

In an embodiment, after the foam spring orientation application software 118 has determined the foam spring 108 configuration for the user, a test configuration may be setup in the bed facility 102 enterprise for the user to try the form spring 108 configuration. Based on the user trying the foam spring 108 configuration at the bed facility 102 enterprise, the foam spring 108 configuration may be modified to improve the bed facility 102 comfort.

In an embodiment, the foam spring 108 configuration may be manually modified by the user or the bed facility enterprise by interchanging form springs 108 and retrying the comfort of the bed facility 102 until a desired comfort has been reached. In another embodiment, the answers to the foam spring orientation application software 118 may be revised and the foam spring orientation application software 118 may provide a new foam spring 108 configuration for the user to try. In another embodiment, the foam spring orientation application software 118 may have provided more than one foam spring 108 configurations and the user may try at least one of the additional configurations to determine if one of the additional configurations provides the desired comfort.

In an embodiment, the bed facility 102 foam spring 108 configuration may be iterated at the bed facility 102 enterprise until a foam spring 108 configuration is determined that provides the desired comfort. In an embodiment, once the final foam spring configuration has been determined, the order for the bed facility 102 with the user's desired foam spring 108 configuration may be placed with a manufacturer for delivery to the user, the configuration may be set in the bed facility 102 enterprise and delivered to the user, or the like.

In an embodiment, after the user has received the bed facility 102 with the user defined foam spring 108 configuration the user may be able to adjust the foam spring 108 configuration, change foam spring 108 firmnesses, or the like. The user may adjust the configuration or firmness of the bed facility 102 because of changing conditions (e.g. the discomfort improves or worsens), to provide a better comfort configuration, or the like. In an embodiment, the user may adjust the foam spring 108 configuration manually by changing the location of the foam springs 108, changing the firmness of the foam springs 108 in certain locations, or the like.

In another embodiment, the user may use the foam spring orientation application software 118 to reconfigure the foam spring 108 configuration. In an embodiment, the user may have been provided a copy of the foam spring orientation application software 118 that the user may operation on the users own computer device.
